DESCRIPTION
WHO CAUSES IT?
Mealybugs are tiny insects that feed on plant sap, belonging to the Coccoidea family. These insects usually cover themselves with a waxy coating that protects them from predators and the environment. Mealybugs can cause significant damage to ornamental and garden plants by weakening them and making them more susceptible to other diseases. Additionally, their sugary excrement can promote the growth of sooty mold fungi, which can affect the aesthetic appearance of plants.
SYMPTOMS
The disease caused by scale insects in ornamental and garden plants manifests itself with the presence of insects attached to the stems, leaves and shoots of the plants. These insects can vary in color and size depending on the species, but are usually visible to the naked eye. Symptoms include weakening of the plant, yellowing and wilting of leaves, production of honeydew (sugar excrement), and the presence of sooty mold fungi on plant surfaces.
